Purse seine cable ring

ABSTRACT

A purse seine cable ring of the type utilized with purse seine nets for anchoring and guiding a draw cable in which the rings have recesses or corners on the inner surface thereof to form a plurality of natural orientation points for minimizing the tendency of the prior art cable rings to orient in one position thereby encouraging excessive wear along one specific area of the ring due to the friction of the draw cable thereon.

PURSE SEINE CABLE RING BRIEF DESCRIPTION OF THE INVENTION The presentinvention relates to a purse seine cable ring and more particularly to apurse seine cable ring having a geometry for distributing frictionalwear.

According to the invention a purse seine cable ring is provided havingeither a plurality of corners on the inside surface thereof or aplurality of recesses. This configuration results in having a pluralityof natural orientation positions to distribute frictional wear of thedraw cable which is common in the prior art smoothsurfaced cable rings.The problem with the prior art smooth-surface cable rings has been theirtendency to orient in one position (since they are not perfectly round)resulting in a maximizing of frictional wear in a given area from thedraw cable. It is pointed out that in this application a corner on theinside surface of the cable ring and a recess will both be treated asrecesses since their result is substantially identical.

An object of the present invention is the provision of a novel purseseine cable ring.

Another object of the invention is the provision of a purse seine cablering having a plurality of recesses on the inner surface thereof.

A still further object of the invention is the provision of a purseseine cable ring having a maximum life.

Other objects and many of the attendant advantages will be readilyappreciated as the same becomes better understood by reference to thefollowing detailed description when considered in connection with theaccompanying drawings in which like reference numerals designate likeparts throughout the FIGS. thereof and wherein:

FIG. 1 is a schematic representation of a preferred embodiment of thepresent invention is situ;

FIG. 2 is a side-elevational view of the embodiment of FIG. 1;

FIG. 3 is a side-elevational view of another embodiment of the presentinvention;

FIG. 4 is a side-elevational view of still another embodiment of thepresent invention; and

FIG. 5 is a side-elevational view of a prior art purse seine cable ring.

DETAILED DESCRIPTION OF THE INVENTION Referring to FIG. 1, a purse seinenet combination is shown generally at 11 having a float line 12 with aplurality of floats 13 tied thereto. Floats 13 are also tied to net 16.A link chain 17 is carried by the bottom edge of net 16 with bridlechains 18 coupled to cable rings 19 by nylon ties 21. A draw cable 22links cable rings 19.

Referring to FIG. 2, a cable ring 19 is shown with a plurality ofrecesses 23 therein formed by the hexagonal shape of cable ring 19.

Referring to FIG. 3, a forge formed cable ring 24 is shown with aplurality of recesses 26. A plurality of protrusions 25 together withthe inner surface of cable ring 24 define recesses 26.

Referring to FIG. 4, a cable ring 27 is shown with a plurality ofrecesses 28.

FIG. 5 illustrates a typical out-of-round prior art cable ring 29.

OPERATION Referring back to FIGS. 1 and 2, it can be seen that therecesses 23 of cable rings 19 will position themselves at the nylon tie21 and /or where cable 22 exerts pressure on the rings 19. Due to theplurality of recesses 23 of rings 19 there are a plurality oforientation spots and hence a plurality of wear spots on the rings 19from friction against draw cable 22.

The same orientation situation will exist with the cable rings 24 and 27of FIGS. 3 and 4, respectively. Here, the recesses are formed in adifferent manner but the plurality of these recesses insure a pluralityof wear spots on the cable rings.

A prior art type of cable ring 29 is shown in FIG. 5 with an exaggeratedellipse. Although the rings are manufactured to be in a circularconfiguration, it has been found as a practical matter that they areusually out of round and, hence, have a tendency to orient themselves inone particular position resulting in excessive wear in one area.

It should be understood, of course, that the foregoing disclosurerelates to only a preferred embodiment of the invention and that it isintended to cover all changes and modifications of the example of theinvention herein chosen for the purposes of the disclosure which do notconstitute departures from the spirit and scope of the invention.

The invention claimed is:

1. In a purse seine net combination consisting of sections of nettingtogether with a plurality of floats tied to the top portion of the netand a plurality of cable rings coupled to the bottom portion of the netwith a draw cable drawn through the cable rings, the improved cable ringcomprising:

a metallic ring dimensioned for receiving a draw cable therethoughhaving a plurality of recesses on its inner surface.
